Ammonia Sensor | GG-NH3-250

Now equipped with SAFECELL technology which checks the electrical viability of the electrochemical cell every 40 seconds. If it is determined that the cell is failed or missing; the 4-20 mA output will drop to 0.5 mA and fault.
Includes a 2 year warranty on sensing element and transmitter.
Designed “food industry tough” for wash-down areas, blast cells, engine rooms, etc.
The GG NH3 uses an ammonia specific electrochemical cell, designed to adapt to any harsh environment from -50°F to +122°F.
